For use in a 12.7" SBR, I'm trying to figure out what factory loads use relatively faster burning powder. (Not set up to handload yet)
This is for 5.56/223, specifically an LWRC 12.7" A3 upper.
Does anyone know of any?
Thanks!
I would love to know what is in all the factory loads I use. I don't hold out any hope that I'll ever know any of them. It's probably like the recipe for Coke.
I'll bet this stuff burns differently than what you have now...fast or slow burning, I'm not sure, but man that 223 bullet moves fast!
